When Mike Tennent decided to take up the challenge to run 2015 in 2015 it didn't seem too bad - until he realised it was 2015 miles not 2015 kilometres as he'd first thought.
He took up the Strava challenge as a way to push his running further, and for a bit of fun.
"I looked at it and my brain thought 2015km. When I looked at it properly and it was miles, that's a bit longer."
The 56-year-old, who has been running for about 10 years, said the challenge was one that suited him well as it didn't require him to run every day - instead he just had to notch up the required amount of just over 3242km over the course of the year.
While he had to overcome a bout of food poisoning which left him sick for a week, and had another week off recovering from a nasty fall, Mr Tennent finished the goal with a few days to spare by running the Tongariro Crossing twice.
